Definitions
- the invention relates to a process for the production of polyvinyl alcohol-stabilized Copolymers based on Vinyl ester and (meth) acrylic acid ester comonomers in the form of them aqueous dispersions and water-redispersible dispersion powders, as well as their use.
- Protective colloid-stabilized polymers are mainly used in Form their aqueous dispersions or redispersible in water Polymer powder in many applications, for example as a coating agent or adhesive for a wide variety of applications Substrates used.
- Air voids in the mortar or concrete is the building material not sufficiently frost-resistant.
- the one with the dispersion powder tempered hydraulic setting systems should also provide better liability towards the unpaid systems.
- DE-A 2214410 (US-A 3883489) describes a method for Production of aqueous dispersions or redispersible in water Dispersion powders based on vinyl acetate-ethylene copolymers.
- the polymerization takes place at one temperature of 60 ° C and in the presence of emulsifiers and polyvinyl alcohol.
- the production of emulsifier-free, purely polyvinyl alcohol-stabilized Vinyl ester (meth) acrylate copolymers is not described.
- EP-A 765898 (US-A 5763508) is a dispersion or a Dispersion powder based on a polyvinyl alcohol stabilized Vinyl acetate-versatic acid vinyl ester-butyl acrylate copolymer known. No information is given about the manufacturing process made.
- EP-A 432811 describes the production of emulsifier-stabilized Vinyl ester (meth) acrylate copolymer dispersions and -Dispersible powders in which the monomer mixture is used as a pre-emulsion is metered in continuously. The production of with polyvinyl alcohol stabilized vinyl ester (meth) acrylate copolymers is not described.
- EP-A 576844 describes, inter alia, the production of vinyl acetate-ethylene-acrylic acid ester copolymer dispersions and -Dispersible powders described.
- the use of emulsifiers is strongly recommended and the use of others Protective colloids as polyvinyl alcohol are described as being advantageous.
- WO-A 99/42504 describes a process for the production of Vinyl ester (meth) acrylate copolymer dispersions described in which the copolymer in the presence of a mixture of nonionic Emulsifier and polyvinyl alcohol is produced, and the Comonomers can be metered in continuously as a mixture.
- EP-A 757065 (US-A 7447578) describes the production of Protective colloid-stabilized vinyl acetate-ethylene copolymers in the form of their aqueous dispersions and redispersible in water Dispersible powders. This makes two-phase polymers accessible with a first ethylene-rich, partially crystalline Phase and a second low-ethylene phase. The copolymerization (Meth) acrylates are not dealt with.
- the invention was therefore based on the object of providing a stable, low viscosity, polyvinyl alcohol stabilized dispersion and corresponding water-redispersible, block-stable dispersion powder based on monomers from the group of vinyl esters, Ethylene and (meth) acrylic acid esters, in particular Methacrylic acid ester, to be made available when in use a completely satisfactory viscosity in cement applications or have cement stability and not the cement setting hinder.
